Bacillus subtilis, also known as hay bacillus and grass bacillus, is a Gram-positive, rod-shaped aerobic and catalase-positive bacterium. B. subtilis is found in soil and the gastrointestinal tract of animals such as cattle and humans. It is commonly included in probiotic supplements as it supports digestion, enzyme production, immune and digestive system health. Produces amylase, lipase and protease.
Ideal for practical investigations into antibiotic efficacy.
All Darwin's bacteria are derived from strains held by the British National Culture Collection (NCTC). These cultures are then sub-cultured before being applied to slopes and sold into schools and colleges across the UK. By sub-culturing we are able to supply quality bacteria at affordable prices. Our bacteria is a maximum of 4 passages away from the Culture Collection’s original. If you require fewer passages, or are purchasing for non-educational purposes, please purchase directly from the NCTC. For full strain information or to purchase directly please click here.
